Abstract
Dioctyl sulfosuccinate was prepared by reaction of sulfosuccinic acid with octyl alcohol, where this compound could be used to manufacture of many different chemical compounds and it is commonly used in the industry, but its high krafft point + 6oC makes proplem in detergents and other manufactures. So, a series of ethoxylated sodium monoalkyl sulfosuccinate (ESMASS) Surfactants were prepared by reaction of poly ethylene glycol with different M.wt (400, 600, 1000 and 4000) with sodium mono alkyl sulfosuccinate (SMASS).
The chemical structures of the prepared surfactants were confirmed by FTIR and H1NMR spectroscopy.
The surface tension of the sythesized surfactants was measured at 25, 35, 45 and 55oC, also the surface active properties were calculated, also thermodynamic micellization and adsorption of these surfactants were calculated.
A series of surfactant and E(14)SMOSS, E(14)SMLSS E(14)SMCSS will chosen to form mixture with SDOSS with different molar ratios to form anionic - nonionic surfactants moities. The surface tension of the synthesized surfactants was measured at 25oC individually or mixing at different molar fraction with the sodium dioctyl sulfosuccinate the surface active properties were calculated and micellization process of the mixture was investigated. The molar ratio of anionic (SDOSS) and an ionic-nonionic surfactants moiety E(14)SMOSS, E(14)SMLSS and E(14)SMCSS in the mixed aggregates were deduced using the regular solution approximation equations.
Depending on the criticle micelle concentration values for each surfactant individually and in mixed systems, the minimum surface tension was exhibited at mixture of (0.6 SDOSS) and 0.4 E(14)SMCSS. The micellar composition of the mixed aggregated were explained and discussed based on the effect of their chemical structures. Activity coefficient (f1, f2), interaction parameter (?) and ideality of anionic-nonionic mixed aggregates were evaluted.
The novel derivatives E(n) SMASS were examined as oil spill dispersants. The obtained results showed that, these derivatives can be used as oil spill dispersant formulation.
